<p>
Berkeley DB is a database library, in which the library is linked into the address space of the
application using it. One or more applications link the Berkeley DB library
directly into their address spaces. There may be many threads of control in this model because
Berkeley DB supports locking for both multiple processes and for multiple threads within a
process. This model provides significantly faster access to the database functionality, but
implies trust among all threads of control sharing the database environment because they will
have the ability to read, write and potentially corrupt each other's data.
